Hi ,<br>
<br>
I have configured kamailio as an IMS server as VM based .<br>
<br>
PCSCF - 10.x.x.179<br>
ICSCF - 10.x.x.79<br>
SCSCF - 10.x.x.73<br>
HSS - 10.x.x.75<br>
<br>
I am using zoiper client for testing the call flow . The *registration is<br>
happening properly* in my both zoiper clients for hss configured users<br>
(alice and bob).<br>
When i am making an *INVITE , *I am getting *403 Forbidden - Domain not<br>
served *error from SCSCF.<br>
<br>
The Call Flow for invite is as follows . call from <a href="mailto:alice@sip.example.com" target="_blank">alice@sip.example.com</a><br>
<br>
zoiper1 (UE) -> PCSCF ( INVITE <a href="mailto:sip%3Abob@sip.example.com" target="_blank">sip:bob@sip.example.com</a>;transport=UDP )<br>
PCSCF -> SCSCF ( INVITE <a href="mailto:sip%3Abob@sip.example.com" target="_blank">sip:bob@sip.example.com</a>;transport=UDP )<br>
SCSCF -> PCSCF (100 trying)<br>
SCSCF -> ICSCF ( INVITE <a href="mailto:sip%3Abob@sip.example.com" target="_blank">sip:bob@sip.example.com</a>;transport=UDP )<br>
ICSCF -> SCSCF (100 trying)<br>
ICSCF -> SCSCF ( INVITE <a href="mailto:sip%3Abob@sip.example.com" target="_blank">sip:bob@sip.example.com</a>;transport=UDP )<br>
SCSCF -> ICSCF (100 trying)<br>
SCSCF -> ICSCF (*403 Forbidden - Domain not served*)<br>
ICSCF -> SCSCF (Request: ACK <a href="mailto:sip%3Abob@sip.example.com" target="_blank">sip:bob@sip.example.com</a> | )<br>
ICSCF -> SCSCF ( 403 Forbidden - Domain not served )<br>
SCSCF -> PCSCF ( 403 Forbidden - Domain not served )<br>
PCSCF -> UE ( 403 Forbidden - Domain not served )<br>
<br>
Below are the alias configuration i have done in pcscf,icscf,scscf nodes<br>
